Credit Check sample

 

The Credit Check sample is a suite of programs that demonstrates these techniques:

• Developing an application that runs in more than one environment

• Using a model queue to create a temporary dynamic queue

• Using a correlation identifier

• Set and passing context information

• Using message priority and persistence

• Starting programs by using triggering

• Using reply-to queues

• Using alias queues

• Using a dead-letter queue

• Using a namelist

• Testing return codes

The application uses these MQI calls:

• MQOPEN

• MQPUT

• MQPUT1

• MQGET for browsing and getting messages, using the wait and signal options, and for getting a specific message

• MQINQ

• MQSET

• MQCLOSE

The sample can run as a stand-alone CICS application. However, to demonstrate how to design a message queuing application that uses the facilities provided by both the CICS and IMS™ environments, one module is also supplied as an IMS batch message processing program.

The CICS programs are delivered in C and COBOL. The single IMS program is delivered in C.

See Table 4 for the CICS application, and Table 1 for the IMS application.
